TTOR/llEl/S mask form the helmet, so to speak, on which support the mask 5 can be revolved about the pivotal connection 21 between the brackets 17 and the members 18 and whereby the said mask can be placed in operative or in inoperative position. When the mask 1s 1n inoperative position, the frame 12 w1l1 come in contact with the head of the wearer and maintain the said mask as a Cask, thereby leaving the face of the wearer free.

rIhe reason for making the mask in the shape of a flattenedsemi-ovoid is to present a convex surface to the rays of the welding or cutting Hame, which will be deflected by said surface, and therefore, eliminate the danger of penetration of said rays ytherethrough. The surfaces presented by the members 10, particularly the upper on e,lmayyl at certain intervals be perpendicular to the rays of the welding or cutting flame and the said rays can pass freely therethrough without coming in contact with the wearer of the mask, as can be seen from Fig. '1, as ample space is left between the front of the mask and the wearers face. The entire mask is, referably, made of aluminum, thereby re ucing its weight. The reason for using the blue and red glasses is that the best results have been obtained after long experiment with said colors.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In a helmet, a mask having a visual opening of two differently colored glasses and a colorless glass in front thereof form-l ing a shield protecting the colored glasses, and means for securing the mask to the head.

2. In a helmet, a mask having a visual opening formed of two colored glasses and a plain glass in front thereof forming a shield for protecting said colored glasses, a support for said mask, and means whereb said mask can be placed in operative or 1n inoperative position on said support.

3. In a helmet, a mask having a visual opening; glasses screening said opening; and means for securing the mask to the head. said glass screening the opening being of red and blue color of the proper density, with a plain glass in the fr'ont thereof shielding -said colored glasses from injury.

4. In a helmet, a mask having a lvisual opening; a series of contacting glasses screening said opening and consisting of plain I window glass and red and blue glasses ofl proper density in the order stated from the front to the rear of the mask; a support for said mask; and means whereby said mask can be placed in operative or in inoperative position on said support.

5. In a helmet, a mask having the shape of a flattened4 semi-ovoid, the flattened portion forming the front of said'mask, said mask having an opening, a frame in said opening; colored and plain glasses removably carried by said frame and forminga visual opening for said mask; a skeleton band adapted to encircle the head; a skull cap carried by said band; members carried by said band; and means connecting pivotally said mask to said members whereby said mask can be rotated on said support.

6. In a helmet, a mask having the shape of a fiattened semi-ovoid, the flattening forming a longitudinal frontal edge on the mask, said mask having a glass-screened, visual opening depressed from the edge, and means for securing the mask to the head.

7. In a helmet, a mask having the shape of a flattened semiovoid, the flattening forming a longitudinal edge at the front, said mask having a central recess apertured at the bottom and converging from the longitudinal edge to the bottom; a plurality of contacting, diHerently colored glasses screening the aperture and forming the visual opening for the mask; and means for securing the mask to the head.

8. In a helmet, a mask having a convex surface diverging from the front to the rear and having the shape of the longitudinal half of a flattened ovoid, the flattening forming a longitudinal edge at the front of the mask, saidmask having a visual opening in the front depressed from the edge; a support for the said mask whereby the same is secured to the head; and means whereby said mask can be revolved on said `support and be placed in operative or in inoperative position.

9. In a helmet, an aluminum mask having the shape of a Hattened semi-ovoid, the fiattening forming a central longitudinal edge at the front of the mask, said mask having a` visual opening depressed from tl1e' edge; differently colored glasses screening said visual opening; andvmeans for securing the mask to the head.

In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses.
